Hw-416-b Pir Sensor Datasheet File

The HW-416-B is notable for its wide input voltage range and low power consumption.

Turning this clockwise increases the detection range (up to ~7 meters). Turning it counter-clockwise decreases the range (down to ~3 meters).

When engineering a circuit, matching component specifications to your system's power and environment constraints is crucial. Below are the verified technical parameters for the HW-416-B module. Electrical Characteristics DC 4.5V to 20V (Commonly driven at 5V) The HW-416-B is notable for its wide input

The HW-416-B timing can be understood in two modes:

The module functions through a dual-element pyroelectric sensor hidden beneath a plastic . platform, this module is a staple for creating

Output remains high as long as motion is detected.

A frequent complaint with the HW‑416‑B is that it triggers constantly after being mounted in a certain location. This is usually caused by:

The HW-416-B features two potentiometers (yellow knobs) and one jumper for customizing behavior. 4.1 Sensitivity Adjustment (Potentiometer)
